MomentJS - Is Before

This method checks if the given moment is before another moment. It returns true or false.

Syntax

moment().isBefore(Moment|String|Number|Date|Array);
moment().isBefore(Moment|String|Number|Date|Array, String);

Example

var isbefore = moment().isBefore('2020-10-21');

Output

Note that the date used inside isBefore is greater than the current date, so we are getting true as the output.

Example

var isbefore = moment([2015, 10, 01]).isBefore([2000, 10, 21]);

Output

With isBefore, we can compare dates from one moment to another. We can also specify the units with isBefore. The units supported are year, month, week, day, hour, minute and second.

Example

Let us consider a working example with units passed to isBefore();

var isbefore = moment([2015, 10, 01]).isBefore([2010, 10, 21], 'year');

Output
